49 HAWKSHEAD LANE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The three 49 HAWKSHEAD LANE sales between April 2005 and March 2025 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the November 2006 sale was for 17% above the HPI. So the extrapolation line tracks at 17% above the HPI over time, until the March 2025 sale, where it falls to 11% above the HPI. The line then continues to track at 11% above the HPI.

This is based on house price deflation of 2.1%, between March 2025 and July 2025, for detached houses, in the Welwyn Hatfield local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 2.1% deflationary decrease is applied to the most recent sale price for 49 HAWKSHEAD LANE of £1,040,000 on 31st March 2025. For the value to have decreased from £1,040,000 to £1,017,702 over the eight months to July 2025, the following assumptions must hold true:
